Motion camouflage is a dynamic type of camouflage by which an object can approach a target while appearing to remain stationary from the perspective of the target. The attacking object simply remains on the line between the target and some landmark point, so it seems to stay near the landmark point from the target's perspective. The only visible evidence that the attacker is moving would be its angle and its looming, the change in size as the attacker approaches. First discovered in certain flies, it has been suggested that missiles could use similar techniques to reduce the time available to targets to respond.

Famous quotes containing the word motion:
“It is the fixed that horrifies us, the fixed that assails us with the tremendous force of mindlessness. The fixed is a Mason jar, and we can’t beat it open. ...The fixed is a world without fire--dead flint, dead tinder, and nowhere a spark. It is motion without direction, force without power, the aimless procession of caterpillars round the rim of a vase, and I hate it because at any moment I myself might step to that charmed and glistening thread.”
—Annie Dillard (b. 1945)
